Bug description: ArrayObject does not call offsetSet when an element is
incremented
Description:
------------
When an element of ArrayObject is incremented (++ operation), the object
does not call its offsetSet method. I've tried overloading all public
methods in ArrayObject: offsetGet is called, but not offsetSet or any
other. Same with decrementing (--). This behaviour makes it impossible to
handle all array modifications by overloading ArrayObject methods in
derived class.
Reproduce code:
---------------
class myArray extends ArrayIterator
{
public function offsetSet($index, $newval)
{
echo "offsetSet called\n";
return parent::offsetSet($index, $newval);
}
}
$a = new myArray(array('x' => 1));
echo "x += 1\n";
$a['x'] += 1; // calls offsetGet, then offsetSet with updated value
echo $a['x']."\n";
echo "x++\n";
$a['x']++; // only calls offsetGet
echo $a['x']."\n"; // but the value gets incremented
Expected result:
----------------
x += 1
offsetSet called
2
x++
offsetSet called
3
Actual result:
--------------
x += 1
offsetSet called
2
x++
3
